From: Julian Ganz <[email protected]> We recently introduced API for registering callbacks for trap related events as well as the corresponding hook functions. Due to differences between architectures, the latter need to be called from target specific code.
This change places hooks for loongarch targets. This architecture has one special "exception" for interrupts and no host calls.
